The bigger the better – Expressions, Idioms, and Slang

Defining "average" as the length of a 20-pound banknote or U.S. dollar bill, which are 5.8 inches (14.9 cm) and 6.1 inches (15.5 cm) long, respectively, the researchers asked women if they were more likely to orgasm vaginally with a longer-than-average or shorter-than-average penis.

Importantly, the axonal length and volume increase much more rapidly than the number of neurons. Furthermore, a proportional increase of neurons and connections would inevitably lead to a rapid increase of synaptic path length, defined as the average number of monosynaptic connections in the shortest path between two neurons ( Watts and Strogatz, 1998; Buzsáki and Draguhn, 2004; Sporns et al., 2004). So that the path length can be maintained, short cut connections can be inserted, resulting in small-world- and scale-free-type networks ( Sporns et al., 2007; Bullmore and Sporns, 2012).

bigger is better Frontiers | Evolution of the human brain: when bigger is better

No doubt he’s the man of your dreams with those perfect face, body and attitude, but…is he the perfect “size”? There are so many different factors," said Komisaruk, who was not involved in Brody's study. "Once it gets to the kind of specifics that they're talking about, I get wary." If you have a thinner penis, choose positions that make for a tighter squeeze. This can be any sex position, really, so long as your partner keeps their legs tight together.

That’s not to say that some people don’t prefer a bigger or smaller one, but that’s a matter of perceived preference, kind of like pineapple on pizza. To each their own.

Front. Neuroanat. 7:28. doi: 10.3389/fnana.2013.00028 In the new study, Brody and his colleagues asked 323 women, mostly Scottish university students, to recall past sexual encounters. They were asked about their recent sexual behaviors as well as how important penile-vaginal intercourse and other sex acts were to them. They were also asked whether penis length influenced their ability to orgasm with vaginal stimulation. Kyoka immediately started drooling at the sight of the half-hard monster in front of her. It was about the width of a 20 oz bottle and at least 18 inches long, it’s size was just as impressive as the previous times she had seen it… and she knew it was only beginning. Wen and Chklovskii (2005) have shown that the competing requirements for high connectivity and short conduction delay may lead naturally to the observed architecture of the mammalian neocortex. Obviously, the brain functionally benefits from high synaptic connectivity and short conduction delays. A magnetic resonance imaging study, furthermore, focusing specifically on the prefrontal cortex, has shown that the volume of the white matter underlying prefrontal areas is disproportionately larger in humans than in other primates ( Schoenemann et al., 2005). It suggests that the connectional elaboration of the prefrontal cortex, which mediates such important behavioral domains as planning, aspects of language, attention and social and temporal information processing, has played a key role in human brain evolution.Rakic, P.
